Admittedly, this unusual memory requires an internal light source, but the amount of illumination required is tiny and consumes less power than the logic circuits that are used to read data in and out.
Because the data are written and read in megabit chunks, holo-drives can transfer data at 20 megabytes per second, far faster than optical drives.
The patents in questions were used in hard drive circuits to read data from high-speed disks.
It will then self-destruct not in flames, its inventors hasten to add, but because contact with the air eventually renders its surface opaque, making it impossible for the laser in a disc player to read the data beneath.
Spintronic PCs are at least a decade off, but the technology has been in use for several years in the magnetic heads that read and write data to hard drives.
They read random data faster than disks and are therefore helpful in search applications.
This is complemented by a second layer of read protection offered by the robust data hold-out algorithm in Plextor's exclusive firmware, thus allowing the drive to achieve total data accuracy even in the long-term.
ENGADGET: Plextor M5 Pro bulges SSD envelope with 94K IOPS and 540MB/s
The NCAA would have one believe that Division II athletic spending is rising no more than total institutional expenditures, which seems dubious to me as I read the data, although admittedly there was a spending spree in all of higher education in most of the period under discussion.
FORBES: The College Athletic Cost Explosion Spreads to Divisions II & III
"Taken together, these inaccuracies and deletions call into question the integrity of the data on adverse cardiovascular events in this article, " it read.
The Race Between Education and Technology is a hefty read filled with data and charts and sometimes long passages written, regrettably, in economese, which likely have been and remain rich fodder for argument among economists.
Until recently the longest living storage media has been magnetic tape which may be kept as long at 30 years in the right environment with good odds that the data can be read back (assuming that the playback devices for that media still exist).
The first set of methods, Read API, will be released in March, 2013 and will allow anyone to retrieve data on petitions, signatures, and responses.
Apparently there are few geologists in the world who have the skill to interpret the logs and read the seismic data from the cretaceous to establish exactly what has been found 6 miles down.
You read books, articles and research, ponder all the data, spin it all around in your head over and over again, and ultimately cannot come to a decision.
The company claims that if optical discs written with this process are stored in a location where they are kept from cracking or chipping the data can be read back years later perhaps even 1, 000 years later.
If viruses do appear in smart tags, said the researchers, they are likely to cause problems for companies that read data off the tags.
Therefore, it is important not to read too much into any one monthly report and it is informative to consider each report in the context of other data that are becoming available.
Maybe attesting to increasingly dynamic labor markets, a key difference between U.S. and, for example, German and Japanese labor markets, the data seem to show a U.S. economy on the rise. (Read Price Stability In 75% of US. Metro Areas By Year-End, Double-Dip Looms).
